Benefits of technology

[0069]In another embodiment, a wearable device is provided that comprises a stretchable interconnect for coupled with one or more electrical components. For example, in one embodiment, a first electrical component and a second electrical component are provided. The stretchable interconnect is disposed between the first electrical component and the second electrical component. The stretchable interconnect has a strain relieving configuration that provides a first regime of elongation in which no strain is applied to a conductor disposed in the interconnect. The stretchable i...

Problems solved by technology

Although extensive complex diagnostic technology is available in sophisticated clinical settings, there are no marketed products for continuously monitoring the health of a baby in-utero.
The current standard of care for monitoring and predicting pregnancy outcome is primitive.
This subjective approach is inaccurate.
It can lead to false alarms, resulting in dangerous maternal stress and an increased burden on the health care system.
Perhaps even worse, it can also lead to false negatives, where despite a...

Processing Guide for Transferring a Structured Metal Thin Film from a Shape-Memory Carrier onto a Silicon Elastomer

[0166]This protocol is meant to serve as a processing guide for transferring wrinkled metal thin films from a substrate (e.g., Grafix Arts polystyrene shrink film) onto an elastomer (e.g., ECOFLEX30™ silicon elastomer). Specific parameters are given for platinum strain gauges and gold interconnects. Adjustments may be made for specific process applications.

[0167]Grafix Frisket Film is mounted to rigid PMMA support. A mask design is laser cut using Grafix Frisket Film using laser settings of 75% power and 100% speed. For convenience, scotch tape is placed across trace width before removing the mask from the support (in order to not distort trace width).

b. Polystyrene (PS) SMP (Grafix Arts)

[0168]Grafix PS sheets are laser cut with laser settings of 78% power, 100% speed and placed concave up (using weights to flatten edges) and then ligned length to length (orient such th...

Densification and Alignment of CNTs using Polyolefin

[0174]This was accomplished by first dispersing CNTs (0.05% wt / v) in a solution of chloroform. CNTs were sonicated for 30 minutes in an ice bath and centrifuged at 10,000 rpm for one hour. This process is also possible in aqueous solution. For example, CNTs can be dispersed into an aqueous solvent when a surfactant, such as sodium dodecyl sulfate (SDS), is present (Yu, J.; Grossiord, N.; Konin, C. E.; Loos, J. Carbon. 2007, 45(3), 618-623). The shape memory polymer was then heated to approximately 60° C. after which drop casting deposition was used to create a thin layer of CNTs. Drop casting is done by pipetting the CNT disperse solution on top of the heated shape memory polymer. The shape memory polymer was then left to dry in a closed container for two hours. In the case of using aqueous CNTs, after the shape memory polymer is dried, it is further washed with an aqueous solvent to remove any surfactants present on the shape memo...

Biaxial or Multi-axial Shrinkage of a CNT Thin Film to Produce a Wrinkled Structure

[0176]One embodiment is a process to densify a CNT thin film to produce wrinkled structure using polyolefin, a chemically resistant shape memory polymer. This was accomplished by first dispersing CNTs (0.05% wt / v) in a solution of chloroform. CNTs were sonicated for 30 minutes in an ice bath and centrifuged at 10,000 rpm for one hour. This process is also possible in aqueous solution. For example, CNTs can be dispersed into an aqueous solvent when a surfactant, such as sodium dodecyl sulfate (SDS), is present (Yu, J.; Grossiord, N.; Konin, C. E.; Loos, J.

Abstract

A wearable sensor apparatus is disclosed that includes a flexible substrate adapted to be coupled with a skin surface of an expectant mother. A conductor is disposed on the flexible substrate. The conductor can include micron-scale invaginations. The conductor can be capable of repeatable variation in resistance when subject to a strain. Also disclosed is a system for monitoring the health of a fetus in utero that includes a wearable sensor apparatus. The wearable sensor apparatus is configured to output a signal responsive to an electrical input. The system includes a computing system with one or more hardware processors. The computing system is programmed to implement a signal processing module configured to access the output signal from the wearable strain gauge and generate an output indicative of health of the baby in utero. The output can be based in part on the received output signal and previously stored correlations between signal data from the wearable strain gauge and observations of the system or of the mother. A user interface module can be provided and can be configured to display an output indicative of health of the baby in utero.

INCORPORATION BY REFERENCE TO ANY PRIORITY APPLICATIONS[0001]Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57.BACKGROUND OF THE INVENTION[0002]Field of the Invention[0003]This application is directed to systems, methods and apparatuses for monitoring the health of a baby in utero.[0004]Description of the Related Art[0005]There are currently approximately 4 million pregnant women in the United States. Although extensive complex diagnostic technology is available in sophisticated clinical settings, there are no marketed products for continuously monitoring the health of a baby in-utero.[0006]The current standard of care for monitoring and predicting pregnancy outcome is primitive. In one prevalent method, the mother is instructed to count the number of times the baby kicks. The American Congress of Obstetricians and Gynecologis...
